Description

[Detailed description of the invention] [Field of industrial use]

The present invention relates to a top support structure for an automobile with a top, and more particularly, to one that is configured to improve watertightness between the top and the vehicle body when the top is attached.

[Prior art and its problems]

Four-wheel drive vehicles for off-road driving are equipped with a hood to cover the loading platform behind the passenger compartment, as seen in Utility Model Application No. 61-6426 and Utility Model Application No. 61-80119. You can see many things done. Such vehicles are provided with a gate-shaped hood frame that is supported between the central part or the rear end of both side frames of the cargo bed so that both legs can rotate in the longitudinal direction of the vehicle body. , and is configured to cover the cargo platform with its rear proper portion supported by a horizontal shaft portion extending in the vehicle width direction between both legs of the top bone. and,
The hood can be fixed to the vehicle body by, for example, attaching the front end to a gate-shaped roll bar installed on the vehicle body to separate the passenger compartment and the cargo bed, the both ends to the side frames of the cargo bed, and the rear end to the cargo bed. This is done by hooking them to the rear frame. By the way, the end of the hood is attached to the vehicle body only by hooking, as described above.
Because the material of the hood makes it impossible to provide an effective sealing means at the attachment point to the vehicle body, the following problems arise, and improvements to these problems have been desired. In other words, since there is inevitably a gap between the end of the hood that is not hooked to the vehicle body and the vehicle body, there is a problem that the watertightness between the hood and the vehicle body is very poor when the hood is in use. It was hot. In this case, the connection between the end of the hood and the side frame or rear frame of the cargo bed is rarely a problem because the end of the hood is installed with the end facing downward in the vertical direction, There are significant problems at the connection between the front end of the canopy, which is fixed facing forward, and the roll bar, and in particular, rainwater and the like can enter the roof from the connection at the top of the roll bar. The present invention was devised under the above-mentioned circumstances, and is designed to improve the watertightness between the top and the vehicle body when the top is in use, and to completely prevent rainwater from entering. The object of the present invention is to provide a top support structure for an automobile with a top.

[Means to solve the problem]

In order to solve the above problem, the present invention takes the following technical measures. That is, in a car with a hood that has a hood that covers the cargo bed behind the roll bar, the lower end is rotatably supported at the middle part in the longitudinal direction of both side frames of the cargo bed, and the upper part of the hood is supported at the horizontal part in the vehicle width direction. The portal-shaped first canopy that supports the rear corner, and the lower ends of both legs at the front parts of both side frames of the loading platform near the roll bar, respectively, rotate in the front-rear direction to both side frames of the loading platform via link members. The canopy can be connected in an upright position, the front edge of the canopy is fixed, and it is closely engaged downward along the rear edge of the roll bar, and the canopy can be folded down along the upper surface of both side frames of the cargo platform. A portal-shaped second hood bone that can assume a reclining position and a hook attached to the lower end of the leg of the second hood bone that takes an upright position are engaged downwardly to move the second hood bone downward. It is characterized by comprising a catch provided on the side frame of the loading platform so as to be retracted and fixed.

[Action and effect]

When the second canopy is rotated forward from the backward tilted position, the canopy fixed to the second canopy is pulled forward so as to cover the cargo bed. At this time, if the first hood bone is fixed to the hood in advance so that the upper horizontal part in the vehicle width direction of the first hood bone supports the upper rear corner of the hood when the hood has a box shape, The first hood rib is pulled by the hood and rotates in the upright direction, and when the second hood bone assumes the upright position, the hood is supported by each of the hood bones and covers the cargo platform in a box shape. In this case, the front edge of the canopy is fixed to the second canopy bone, so
It is not necessary to fix the above-mentioned edge to the roll bar by hooking or the like as in the conventional example. Note that the side and rear hem portions of the canopy are fastened to the side frames and rear frame of the cargo platform by hooks or the like, as in the past. On the other hand, when removing the hood, remove the hooks at the hem and rotate the second hood bone, which assumes an upright position, to fall backwards, folding the hood into a backward position. As a result, the first hood rib, which is released from the tensile force from the hood, also collapses and rotates due to its own weight, and the hood is stored on the loading platform.
In this way, when storing the top, it is only necessary to rotate the second top rib to take a backward tilting posture, and there is no need to remove the top from the top bone one by one as in the conventional example. In the above-described state of use of the canopy according to the present invention, the second portal-shaped canopy rib, which has a shape corresponding to the portal-shaped roll bar, is in close contact with the rear edge of the roll bar in the upright position. The close contact state is maintained as follows. That is, first, the space between the roll bar and the second hood bone is configured such that the second hood bone closely engages with the rear edge of the roll bar from above, and the upper surface of the rear edge of the roll bar The close engagement state of the roll bar is achieved by hooking the hook attached to the lower end of the leg of the second canopy downward and pulling it downward using a catch attached to the side frame of the cargo platform. maintained. As a result, the second hood rib is always in close contact with the roll bar with an appropriate vertical pressing force.
On the other hand, since the front edge of the hood is fixed to the second hood bone, when the hood is in use as described above, the roll bar and the front edge of the hood are connected via the second hood bone. The second hood rib, which is in a connected state and thus performs a sealing function, provides sufficient watertightness to the joint between the roll bar and the hood. Therefore, the conventional problem of rainwater or the like entering the luggage compartment from the connecting portion is completely solved. Further, in the present invention, by providing a link member between the lower end portions of both legs of the second canopy bone and the both side frames of the loading platform, the substantial rotation fulcrum of the second canopy bone is set on the both side frames of the loading platform. Even though it is set at a part away from the roll bar, it is possible to take the above-mentioned standing posture in which the second hood bone is in close contact with the roll bar, so that the stable effects of the present invention can always be enjoyed. We take this into consideration. In other words, in order for the second hood bone, which rotates in the longitudinal direction of the vehicle body, to take an upright position in which it is in close contact with the roll bar, and a backward leaning position in which it falls backward, it is necessary to The pivot point of both legs of the roll bar is generally set at the lower end of both legs of the roll bar, so that the second hood bone and the roll bar are always in close contact at least near the pivot point. It is normal for this to happen.
However, if a sealing material such as a weather strip is attached to the rear edge of the roll bar to which the second hood bone is crimped when the second hood bone assumes an upright position, the second hood bone Rotation is performed while always in contact with the sealing material near the rotation fulcrum. For this reason, as the second hood rib repeats rotation, the portion of the sealing material near the rotation fulcrum is worn out, and the sealing effect between the second hood bone and the roll bar in the vicinity of the rotation fulcrum is affected. The problem arises that it cannot be maintained for a long period of time. Under these circumstances, in the present invention, by providing a link member, the second hood bone can assume an upright posture without rotating about the rotational fulcrum as described above, and the roll bar is The above problem does not occur even if a sealing material is provided between the two by pressing the second canopy bone downward against the rear edge to form a close contact with these pockets. That's what I do. Furthermore, in the present invention, the catch provided between the legs of the second hood bone and the cargo bed side frame allows the roll bar and the second hood bone to be connected while pulling only the legs of the second hood bone downward. Since the structure is configured to achieve close contact between the hoods, the above-mentioned catch only needs to be operated in two places, making it extremely easy to change to the state in which the hood is used. A high degree of watertightness is maintained between the second hood rib or the hood. In addition, as mentioned above, attaching and removing the canopy can be done by a simple operation such as rotating the second canopy bone between the upright position and the backward leaning position, and it does not cause any structural trouble. The top support structure of the present invention greatly improves the work of attaching and removing the top, which has been thought to be impossible. As described above, in the present invention, when the top is in use, the watertightness of the connection between the front edge of the top and the roll bar is improved, thereby solving the drawbacks of the top. The watertightness between the second hood rib and the roll bar, which performs a sealing function between the hood and the roll bar, is configured to be stable for a long period of time, further enhancing the effects of the present invention. It also improves workability.

[Explanation of Examples]

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing the overall configuration of this example, and in this figure, the top 1 is schematically shown with imaginary lines so that the top support structure of this example can be clearly understood. As shown in this figure, the canopy support structure of this example has a gate-shaped first structure that is rotatably supported at the center in the longitudinal direction of the vehicle body of both side frames 4, 4 of the cargo bed 3 located behind the roll bar 2. Provided between the top rib 5 and the lower end portions of both leg portions 12, 12 and the above-mentioned side frames 4, 4 at the front portions of both side frames 4, 4 of the loading platform 3, at a portion away from the roll bar 2, respectively. A gate-shaped second hood rib 11 is rotatably supported via link mechanisms 13, 13, and the front edge of the hood 1 in the longitudinal direction of the vehicle body is fixed to the second hood rib 11. There is. As shown in FIG. 5, the first canopy rib 5 is rotatably supported by the lower ends of both legs 6, 6 on the both side frames 4, 4 via a handle screw shaft 8 which is bolted thereto. has been done. In addition, as shown in FIG. 6, the top 1 has a box-shaped upper rear corner portion 1a that the top 1 exhibits when attached to the vehicle body as shown in FIG. An appropriate number of band members 9 having Velcro tapes 10, 10 provided thereon are sewn at several locations in the vehicle width direction. By holding the upper vehicle width direction horizontal portion 7 extending in the vehicle width direction between the upper end portions of both leg portions 6, 6 of the first hood rib 5 by the band members 9, the hood can be fixed. The rear part of 1 is fixed to the first hood bone 5. On the other hand, the second hood rib 11 is connected to the link mechanism 1.
3 and 13, it is possible to take an upright position in which it is in close contact with the rear part of the roll bar 2 as shown in FIG. It is supported so that it can rotate in the longitudinal direction of the vehicle body. In addition, in the second hood rib 11,
A retainer member 16 having a gate-shaped shape corresponding to the second hood bone 11 and having a hood fixing portion 17 formed by curving the tip inward covers the entire outer circumferential surface of the second hood bone 11. It is fixed in such a way that it is fixed. Then, as shown in FIGS. 3 and 4, the hood 1
The front end of the elastic body 18 is wrapped around the hood fixing part 17 so as to cover the retainer member 16, and the elastic body 18 is crimped into the hood fixing part 17, thereby fixing it to the retainer member 16 or the second hood rib 11. It is worn. Note that, as shown in FIG. 2, the lower ends of both legs 12, 12 of the second canopy 11 are such that even if the second canopy 11 is vigorously rotated to take an upright position, the loading platform 3 cannot be moved. Cushion rubber 23 is used to prevent damage to the side frame 4 and the leg portions 12 that come into contact with the side frame 4.
is installed. As shown in FIGS. 3 and 4, in this example, at the rear of the roll bar 2, there is a ceiling section 2a or both leg sections 2a, similar to the resin top specification vehicle.
A flange portion 2c is formed extending rearward over the entirety of b and 2b, and a weather stop 19 is attached to the tip of this flange portion 2c.
When the second hood rib 11 is placed in an upright position, the inner surface of the retainer member 16 comes into pressure contact with the weather strip 19, thereby achieving a close contact between the roll bar 2 and the second hood rib 11. That's what I do. In order to maintain the second hood rib 11 in an upright position, hooks 20 that engage with the hook holes 11a of the second hood rib 11 are fixed at several locations on the rear part of the roll bar 2 along the vehicle width direction. As shown in FIGS. 1 and 2, hooks 21 are provided on both side frames 4, 4 of the cargo platform 2 to hang on hooks 21 provided at the lower ends of the legs 12 of the second canopy 11. A catch 22 with a catch 22a is fixedly mounted in each case. Now, as shown in FIGS. 1 and 2, the link mechanism 13 described above is a link member whose one end is pivotally supported by a ring bracket 14 fixed on the side frame 4 of the loading platform 2. link arm 1
5 is pivotally connected to the lower end of the leg 12 of the second canopy 11. And, with this link mechanism 13, 13,
Even if the substantial rotational fulcrum of the second hood rib 11 is set at a location away from the roll bar 2 on both side frames 4, 4 of the loading platform 3 as in this example, the second hood rib 11 is It is possible to take a standing posture in close contact with the roll bar 2. That is, when the second hood rib 11 is moved between the pivot points of the roll bar 2 and the link brackets 14, 14 by the link mechanisms 13, 13, the link As the arms 15, 15 fall down and rotate forward, they are moved parallel to the roll bar 2 while drawing a 1/4 arc trajectory, and are brought into a standing position close to the roll bar 2 as shown by the solid line in Fig. 2. It is configured to take This results in
This prevents the sealing effect of the weather strip 19 from decreasing due to repeated rotation of the second hood rib 11. That is, the second hood bone 11 rotates in the front-rear direction.
However, in order to be able to take the above-mentioned standing posture and backward leaning posture, the rotational fulcrum of the second hood rib 11 is set at the lower end of the leg 2b of the roll bar 2, and at least the rotational fulcrum is set at the lower end of the leg 2b of the roll bar 2. Normally, the retainer member 16 and the weather strip 19 are always in contact with each other in the vicinity. but,
In such a case, due to the repeated rotation of the second hood rib 11, the portion of the weather strip 19 near the pivot point is gradually worn out, and as a result, the weather strip 19 is not evenly distributed over a long period of time. There is an inconvenience that the sealing effect cannot be enjoyed. Therefore, in the present invention, the link mechanisms 13, 13
By providing this, the second hood rib 11 is configured to be able to move between the upright position and the backward tilted position without having to rotate about the rotation fulcrum as described above, and the roll bar 2 and This prevents deterioration of the sealing effect between the second hood rib 11 and provides stable watertightness between the two for a long period of time. In the hood support structure of this example configured as described above, when the hood 1 is attached to the vehicle body, the second hood rib 11 may be rotated forward in the longitudinal direction of the vehicle body. Then, the canopy 1 fixed to the second canopy rib 11 is pulled forward while covering the cargo platform 3, and along with this, the first canopy rib 5 fixed to the rear of the canopy 1 is also attached to the canopy 1. Stand up and rotate while pulling. Then, when the second canopy bone 11 takes the upright position, the canopy 1 has its front end supported by the second canopy bone 11 and the upper rear corner part 1a supported by the first canopy bone 5. , covers the loading platform 3 in a box shape. After this, the hook portion 22a of the catch 22 is hooked to the hook 21 of the second canopy 11, and the second canopy 11 is fixed while being pulled downward in the upright position.
The side hem portions and rear hem portions of the top 1 are hooked to hooks 24 provided on the outer surfaces of the side frames 4, 4 and the rear end portion 3a of the cargo platform 3, thereby fixing the top 1 to the vehicle body. On the other hand, when storing the canopy 1 and the loading platform 3, the steps for attaching the canopy 1 and the loading platform 3 are reversed, and the folded canopy 1 is further rolled up onto the loading platform 3 and attached to the loading platform 3 using a wrapping band (not shown). Fix it. At this time, the second hood rib 11 has taken a backward leaning position and is in a state where it has collapsed onto both side frames 4, 4 of the loading platform 3, and the first hood rib 5 has also collapsed onto the rear frame 3a of the loading platform 3. state. In this example, as shown in FIG. It is defined to be equal to the length (b+c) that is the sum of the length c of the leg portion 12, and the length d of the leg portion 6 of the first hood bone 5 and the first hood bone 5.
The distance e from the pivot point to the rear end of the loading platform 3 is equally defined. Therefore, even if the first canopy rib 5 and the second canopy rib 11 fall onto the loading platform 3, each of the canopy ribs 5 and 11 will not protrude from the loading platform 3. There is no problem in attaching the spare tire 25. By the way, when installing the hood as described above,
The second hood rib 11, to which the front edge of the hood 1 is fixed, and the roll bar 2 are in perfect contact via the weather strip 19 or the retainer member 16. That is, when the hood 1 is attached to the vehicle body, the second hood rib 11 functions as a sealing member, and the front edge of the hood 1 is connected to the roll bar 2 through the second hood rib 11 without a gap. . Therefore, there is no problem such as rainwater entering from the connection between the front edge of the top 1 and the roll bar 2 as in the conventional example. In addition, when attaching and removing the top 1, the second top rib 11 is rotated between the upright position and the backward tilted position, so that the top 1 is placed over the loading platform 3 in a box shape. , it can be easily folded onto the loading platform 3. Therefore, in the top support structure of this example, the work of attaching and removing the top 1 is much easier than in the past. As mentioned above, in the canopy support structure of this example,
The new structure includes a second hood rib 11 that supports the front edge of the hood 1 and performs a sealing function between the hood 1 and the roll bar 2. This completely solves the problem of watertightness when using a canopy. Furthermore, link mechanism 1
3, and the connection structure that rotatably connects the second hood rib 11 to the vehicle body is also devised, thereby improving watertightness between the second hood rib 11 and the roll bar 2, that is, in this example. This ensures that the effects can be enjoyed stably for a long period of time. In addition, in this example, the rear part of the roll bar 2 is formed in the same manner as the resin top specification vehicle as described above, so that the second hood rib 11 can perform a sealing function against such a roll bar 2. . Therefore, even on a car with a resin top specification, which is different from a car with a hood like this example, if a support means for the hood rib is provided, the hood can be attached while maintaining sufficient watertightness as in this example, It is also convenient in terms of compatibility. Note that the scope of the present invention is not limited to the embodiments described above. For example, the design of the support structure for the second canopy can be modified in various ways other than the above embodiments.
